New device for correcting sagittal plane imbalance launched


NuVasive has launched the ALIF ACR—anterior lumbar interbody fusion; anterior column realignment—in the USA. The device is designed to correct the sagittal plane imbalance that results from advanced degeneration and is designed to achieve the same correction capabilities as traditional techniques while providing the benefits associated with less invasive anterior approaches.

According to a press release, the hyperlordotic implants developed for the ALIF ACR procedure are the company’s latest innovative advancement in an effort to improve sagittal plane deformity correction. The press release reports that typical ALIF implants only offer 8 to 15 degrees of lordosis, which presents a challenge when attempting to restore natural lumbar lordosis. The implants developed for the ALIF ACR procedure offer a 20-degree and 30-degree hyperlordotic footprints and may improve sagittal balance restoration capabilities.

“The ability to restore natural lumbar lordosis of 50 to 60 degrees through a two-level ALIF ACR procedure without requiring a posterior osteotomy represents a significant advancement in spinal deformity correction,” said Chris Shaffrey, professor of Neurological Surgery, Spine division director, University of Virginia, USA.
